Get multiple file data information after upload success codeigniter - codeigniter

Question

When I upload multiple images I would like to be able to display each file name.
I can upload the file fine in to the upload folder, but when I try to get the multiple file_name data it shows error below.
I get this error below
Severity: Warning Message: Illegal string offset 'file_name' Filename:
page/Page_add.php Line Number: 110
Which is here in success part of upload function
$upload_info = $this->upload->data();
foreach ($upload_info as $upload_data) {
echo $upload_data['file_name']; // Line 110
}
Do upload function
public function do_upload() {
$directory = FCPATH . 'uploads/';
if (is_dir($directory)) {
foreach ($_FILES as $field_name => $value) {
if ($value['name'] != '') {
$this->load->library('upload');
$this->upload->initialize($this->do_upload_options());
if (!$this->upload->do_upload($field_name)) {
$this->form_validation->set_message('do_upload', $this->upload->display_errors());
return FALSE;
} else {
$upload_info = $this->upload->data();
foreach ($upload_info as $upload_data) {
echo $upload_data['file_name'];
}
}
}
}
} else {
$this->form_validation->set_message('do_upload', 'Cannot Find Directory' .' '. $directory);
return FALSE;
}
}
public function do_upload_options() {
$config = array();
$config['upload_path'] = FCPATH . 'uploads/';
$config['allowed_types'] = 'gif|png|jpg';
$config['max_size'] = '30000';
$config['overwrite'] = TRUE;
$config['max_width'] = '0';
$config['max_height'] = '0';
return $config;
}
Each field name has its own name="" example name="fileupload_extra_image0" the number at the end is automatically generated
Vardump
array(2) { ["fileupload_extra_image0"]=> array(14) { ["file_name"]=> string(17) "ci_logo_flame.jpg" ["file_type"]=> string(10) "image/jpeg" ["file_path"]=> string(49) "C:/Xampp/htdocs/riwakawebsitedesigns-cms/uploads/" ["full_path"]=> string(66) "C:/Xampp/htdocs/riwakawebsitedesigns-cms/uploads/ci_logo_flame.jpg" ["raw_name"]=> string(13) "ci_logo_flame" ["orig_name"]=> string(17) "ci_logo_flame.jpg" ["client_name"]=> string(17) "ci_logo_flame.jpg" ["file_ext"]=> string(4) ".jpg" ["file_size"]=> float(3.61) ["is_image"]=> bool(true) ["image_width"]=> int(100) ["image_height"]=> int(100) ["image_type"]=> string(4) "jpeg" ["image_size_str"]=> string(24) "width="100" height="100"" } ["fileupload_extra_image1"]=> array(14) { ["file_name"]=> string(10) "family.png" ["file_type"]=> string(9) "image/png" ["file_path"]=> string(49) "C:/Xampp/htdocs/riwakawebsitedesigns-cms/uploads/" ["full_path"]=> string(59) "C:/Xampp/htdocs/riwakawebsitedesigns-cms/uploads/family.png" ["raw_name"]=> string(6) "family" ["orig_name"]=> string(10) "family.png" ["client_name"]=> string(10) "family.png" ["file_ext"]=> string(4) ".png" ["file_size"]=> float(828.1) ["is_image"]=> bool(true) ["image_width"]=> int(670) ["image_height"]=> int(450) ["image_type"]=> string(3) "png" ["image_size_str"]=> string(24) "width="670" height="450"" } }
